Hi Santosh,
Almost you need to create COPY of present bw production at quality system.
So most of the data flow design may be there. first check all data sources, info packs,dtp are in place.
on the same you have all process chains also.
so start pulling full loads and do the init.
once full load init was over for respective target related data flow, next time onwards you can trigger designed process chains on daily basis.
like that way you can do for all existing data flow and schedule respective process chains.
Thanks
